Thanks for your reply...code is working beautifully

I am using space key to initialize a thread which starts flashing text on the screen. Now the problem is that if i press the same key again then same thread gets started again and t.abort or t.suspend is not working either.
My idea is pause the thread if the same key is pressed again...like an on off button..

If e.KeyCode = Keys.Space Then

Dim value As Boolean = False

Control.CheckForIllegalCrossThreadCalls = value

Dim t As Thread

t = New Thread(AddressOf rsvp)

If t.IsAlive = False Then

t.Start()


Else : t.Abort()

End If
End If
